clisp-devel

With today's commits CLISP builds fine on MacOS X 10.3.5 (Darwin 7.5.0),
in all 10 build variants that I used on x86.
The test suites have proven useful once again: Each of sacla-tests and
ansi-tests found a long-standing bug that for some reasons didn't show
up on x86 platforms.
The only remaining TODO items for this platform are:
- Release libsigsegv-2.2; it has Darwin 7 support.
- Add code to libopen() to work around a dlopen() deficiency on this
platform.
